vm: limit sparse page init loop to last free page frame
...
when the sector coverage mode is set to free, the loop that initialises the vm_page structs for free and reserved pages is limited to the same upper bound that is used to calculate the sector size and count.

kernel: add kernel.early-console and kernel.console boot args
...
kernel.early-console is used to specify which output device the
kernel boot log should be written to. the first thing the kernel
does on boot after initialising the bootstrap processor is initialise
the early console, making it useful for debugging problems that
occur early in the boot process. this arg accepts a list of hard-coded
values for output devices, such as tty0 for the display or ttyS0
for the serial port. the exact values supported will depend on the
platform.
once all drivers are loaded, the kernel switches to the device specified
by kernel.console for output. unlike kernel.early-console, this arg
specifies the name of a tty device in /dev/tty. this means that, not
only are more devices supported (any device provided by a tty driver),
but the kernel can also get input from the user using this console too
(not used by the kernel itself, but will be used by the user to interact
with userspace programs, like the shell).
